Model.surfacedisplaynormals

Model.surfacedisplaynormals(collection, size)

Turns on the display of surface normals. The display type is defined by Model.setsurfacenormalsdisplaytype().

Parameters:

• collection (Collection) – The collection containing the entities to display their normals. Valid entities are surfaces, solids and components.

• size (double) – Specifies the size of the normal graphics to be drawn, if vector normal display is set. If set to zero, the vector is drawn at 10% of the screen size.

Example

Turn on the display of normals for surfaceswith IDs 1 - 10 at 10 % screen size

import hm
import hm.entities as ent

model = hm.Model()

# Creating a collection that contains the surfaces with IDs 1-10
filter_surfaces = hm.FilterByEnumeration(ent.Surface, list(range(1, 11)))
surfaces_collection = hm.Collection(model, filter_surfaces)

model.surfacedisplaynormals(collection=surfaces_collection, size=0)
